High Quality CE certified Relay Testing Device Good Price Relay Test Set 6 Phase Protection Relay Tester

This six phase microcomputer is certified by CE certificate, and it's in our Secondary Injection Relay Test kit

1. Voltage and current test

Select a phase voltage or a phase current as the variable, select automatic or manual test mode change, until the relay acts. When the voltage is greater than 125V and the current is greater than 40a, the line voltage output can be used, such as UAB, UBC and UCA. The current can be output in two-phase parallel or three-phase parallel mode. Note that the current phase should be in the same phase. The high current output time should be as short as possible, and the initial value can be set as 90% of the setting value to shorten the test time. When doing multi-stage over-current protection, it can directly output 1.2 times of current setting value, so that the measured action time is accurate.

2. Frequency test

The default value of the initial frequency is 50 Hz, which can be modified by the user. Select variable frequency, input

appropriate frequency step, and click start test. All current and voltage frequencies change.

3. Power direction test

he protection device generally adopts 90 degree wiring mode, and the low voltage setting is 60V. During the test, UA = 60V and phase is 0 degree; UB = 0V and phase is 0 degree; in this way, the line voltage UAB = 60V and phase is 0 degree, and then the voltage is fixed. The amplitude of IC is fixed (generally 5A), and the phase of IC is changed to measure the two action boundary angles. The 90 degree wiring mode is output in the way of "UAB, IC", "UBC, IA" and "UCA, IB".0 degree wiring is output in the way of "UAB, IA", "UBC, IB" and "UCA, IC". Sensitivity angle = (boundary angle 1 + boundary angle 2) / 2.
